An analytical observation was carried out on clinical symptoms, physical findings, etiology, precipitating factors, pulse rate, and blood pressure manifested by 115 patients admitted to the Kyung hee university Hospital under the diagnosis of congestive heart failure for a period of October 1971 to September 1974. The results were as follows: 1. The disease affected female 1.4 times more frequently than male and occured most frequently in the 6th decade (26.1%), and its incidence decreased in the 7th decade (22.6%). 2. The important causes of congestive heart failure were hypertensive heart disease (39.7%), rheumatic heart disease (26.1%), cor pulmonale (13.9%), atherosclerotic heart disease (6.1%), postpartum heart failure (6.1%) and pericardial disease (3.5%). The unknown etiology was 3.5% of all cases. 3. The most common precipitatiog factors of the 106 patients of congestive heart failure were infections (59.5%), especially in the upper respiratory tract infection (37.8%). The physical exertion, pregnancy and labor, psychic stress, angina, myocardial infarction, and discontinuation of Tapazol and digitalis were followed. 4. The most common symptoms and signs were the dyspnea (93%), and the next common were pulmonary rales (65.2%), hepatomegaly (59.1%), distention of cervical vein (55.7%), pitting edema (44.3%) and cardiac murmur (38.3%) on admission. 5. The increased pulse rate over 101/min. was about 38.3%, but less than 60/min. was found in 4.3% only. 6. The electrocardiographic findings were abnormal except one case out of 107 cases. The left ventricular hypertrophy (48.1%), atrial fibrillation (24.5%), and bundle branch block (21.7%) were frequently observed. 7. The range of systolic blood pressure measured in 43 patients who had been suffered from hypertensive heart disease were disclosed that 221-240 mmHg (23.3%), 161-180mmHg (20.9%), and 181-200mmHg (20.9%) in order.

An analytic study on 431 cases of cardiac conduction disturbance has been made by review of the clinical records and electrocardiograms taken from the adult patients registered at Kyung Hee University Hospital for 3 years from May, 1973 to April, 1976. 1. The total incidence of conduction disturbance was 6.50%, the atrioventricular block 3.14% and the intraventricular block was 3.36% of total 6,616 cases of E.C.G. reviewed. Among of these, the first degree atrioventricular block was 3.02% which was the most common occurred one, the incomplete right bundle branch block was 2.25% and the complete right bundle branch block was 0.57%. 2. The ratio of male to female was 1.6:1 for the first degree atrioventricular block, and 1.6:1 for the incomplete right bundle branch block, 2.5:1 for the complete atrioventricular block, 2:1 for the left bundle branch block, and 1.7:1 for the complete right bundle branch block. The first degree atrioventricular block was seen most frequently in the fifth and sixth decade of age group, and the third degree block was over 40 years. The incomplete right bundle branch block in order was forth decade, third decade and fifth decade. The complete right bundle branch block and left posterior hemiblock were common in the sixth decade. The left bundle block and the posterior hemiblock were common in fifty years of age group. 3. The cardinal underlying diseases of the first degree atrioventricular block among cardiac diseases group in order of frequency were: hypertensive heart disease (25.0%) arteriosclerotic heart disease (8.0%) and rheumatic valvular heart disease (5.0%). The most common etiology of those non-cardiac disease group was neuropsychiatry disorder (11.5%) and the next was infection (11.0%). 4. All of the complete atrioventricular block were associated with the cardiac disease, that is, 57.0% with arteriosclerotic heart disease, 28.5% with pericarditis and 14.3% with hypertensive heart disease, respectively. 5. The cardinal underlying disease of the incomplete right bundle branch block in order of frequency were: hypertensive heart disease (10.7%), arteriosclerotic heart disease (8.1%) among the cardiac disease group, and infections (15.4%) among the non-cardiac disease group. The incidence of healthy persons was 14.1%. 6. Those of complete right bundle branch block in order of frequency were: arteriosclerotic heart disease (13.2%), and hypertensive heart disease (10.1%) among the cardiac disease group, and infection(13.2%) and neurosis (10.1%), respectively among the non-cardiac disease group. 7. The major etiologies of the left bundle branch block was hypertensive heart disease and arteriosclerotic heart disease (33.3% each), and that of left posterior hemiblock was showed arteriosolerotic heart disease and cor-pulmonale. The most common etiological disease of the left anterior hemiblock was hypertensive heart disease in cardiac disease group, and infection and gatrointestinal disease in non-cariac disease group. 8. The abnormal electrocardiographic findings with the first degree atrioventricular block were left ventricular hypertrophy (24.8%), sinus tachycardia (11.0) and sinus bradycardia (5.8%). Those with the complete atrioventricular block were right ventricular hypertrophy (15.8%) and left bundle branch block (15.8%). In complete right bundle branch block, the majority (52.5%) showed single sign without other abnormality on E.C.G. In the left bundle branch block, there were 18.9% of left ventricular hypertrophy and 15.7% of first degree atrioventricular block. In the left anterior hemiblock, there were 28.5% of right bundle branch block, and 19.0% of right ventricular hypertrophy. In the left posterior hemiblock, there were 40.0% of atrial fibrillation and 20.0% of left atrial hypertrophy.

PURPOSE: The aim of this study was to analyze the osteogenic effect of cultured rabbit mesenchymal stem cells(MSCs). MATERIALS AND METHODS: MSCs were obtained from rabbit femur and were cultured in a Dulbecco's Modified Eagle's Medium(DMEM) with beta-glycerophosphatate, L-ascorbic acid, and dexamethasone to proliferate and differentiate into osteoprogenitor cells until 12 weeks. The expression of osteogenic markers was detected by reverse transcription-polymerase chain reaction(RT-PCR) and the release of osteocalcin was measured by Enzyme-linked Immunosorbent Assay(ELISA). MSCs that were cultured on the porous poly-L-lactic-co-glycolic acid(PLGA) scaffold were implanted into athymic nude mouse to observe the osteogenic activity. RESULTS: As the time, we observed osteoblastic-like cells on the culture flask. Mineralized nodules were observed at 3-4 weeks. Osteogenic markers such as osteopontin, osteonectin, type I collagen, and alkaline phophatase were all identified at 2 weeks. But, expression of osteocalcin was only detected after cells differentiation. The amount of osteocalcin which is a specific protein in osteoblast, increased gradually from 2 weeks until 7 weeks. Scanning electron microscopy revealed that the MSCs were well adhered and proliferated within the PLGA scaffold. Immature bone was identified after 10 weeks in the histological examination of transplanted cell-scaffold composit. CONCLUSION: Our results demonstrate gradual differentiation of MSCs into osteoblastic cells. The adhesion and proliferation of the cells within the biodegradable scaffold represents the possibility of bone formation using cell-scaffold composites.

PURPOSE: The purpose of this study was to report the clinical result of subtrochanteric fractures which were treated with Rowe plate. MATERIALS AND METHODS: 30 cases of subtrochanteric fracture, which were operatively treated with Rowe plate, were evaluated clinically and radiographically. All patients were followed for at least 1 year. RESULTS: Primary bony union was achieved in 28 cases (93%) . Bony union after secondary operative procedure was obtained in 2 cases (6.7%) . The fracture was united within 6 months except 3 cases. As complications, coxa vara deformity under 120. of neck-shaft angle was observed in 2 cases and one of them was associated with limb shortening more than 1 cm. CONCLUSION: We could obtain satisfactory clinical results with the use of Rowe plate in treating some selected cases of subtrochanteric fracture. The good indications for the use of Rowe plate seem to be some subtrochanteric fracture associated with intertrochanteric fracture, long spiral subtrochanteric fracture, comminuted subtrochanteric fracture with multiple large fragment, and subtrochanteric fracture in deformed proximal femur.

PURPOSE: To determine the in vivo bone formation on an osteoblastic cells-scaffold composite and the best scaffold for bone formation. This study focused on the three-dimensional culture of osteoblastic cells using various tissue-engineered scaffolds and compared the suitability of those scaffolds. MATERIALS AND METHODS: Mesenchymal stem cells were harvested from New Zealand white rabbits and were differentiated into osteoblastic cells. The expression of osteogenic proteins in osteoblastic cells was observed by RT-PCR and a phase of mineralization was checked using von Kossa staining. In addition, three-dimensional cultured osteoblastic cells-scaffolds composites using a variable scaffold were observed by scanning electron microscopy. The cell-scaffold composites were transplanted into athymic nude mice. X-ray, a histochemical study, and immunohistochemistry were used to evaluate the in vivo bone formation. RESULTS: The mesenchymal stem cells proliferated quite well in the early phase and differentiated into osteoblastic cells by an inducing substance. The osteoblastic cells were observed as spindle and polygonal shapes and were mineralized. Expression of the osteoblastic proteins was observed continuously after 2-3 weeks. The amount of osteocalcin secretion increased for 6-7 weeks. The osteoblastic cells adhered more to the human and porcine bone than to the hydroxyapatite-scaffold. In the case of the PLGA scaffold, the cells proliferated and formed a net-like structure but did not adhere well. No Living cells were observed in the calcium alginate scaffold. However, after the in vivo transplant, abundant cells and new tissue were observed within the human bone, porcine bone, hydroxyapatite, and PLGA but not within the calcium alginate scaffold. CONCLUSION: In the three-dimensional cultures, natural bone was found to be a more effective and suitable scaffold for cell culture than the various synthetic polymers.

BACKGROUND: Blood pressure (BP) control is the most-established method for the prevention of chronic kidney disease (CKD) progression. However, the ideal BP target for CKD patients is still under debate. METHODS: We performed a survey of regular registered members of the Korean Society of Nephrology to determine physician perceptions of BP control in patients with CKD. In addition, we evaluated the target BP achievement rate using data from the APrODiTe-2 study. RESULTS: Two-thirds of physicians considered the target BP for CKD to be < 130/85 mmHg. The systolic BP (SBP) thresholds for diabetic CKD, proteinuria ≥ 300 mg/day, 30 ≤ glomerular filtration rate (GFR) < 60 mL/min/1.73 m2, age < 60 years, and the presence of atherosclerotic (ASO) complications were significantly lower than the SBP thresholds of the opposite parameters. The three major hurdles to controlling BP were non-compliance with lifestyle modification and medications, and self-report of well-controlled home BP. Most physicians prescribed home and ambulatory BP monitoring to less than 50% of their patients. The target BP achievement rates using the SBP thresholds in this survey were as follows: non-diabetic (69.3%); diabetic (29.5%); proteinuria < 300 mg/day (72.3%); proteinuria > 300 mg/day (33.7%); GFR ≥ 60 (76.4%); GFR < 30 (47.8%); no evidence of ASO (67.8%); and the presence of ASO (42.9%). CONCLUSION: The target BP was lower in patients with higher cerebro-cardiovascular risks. These patient groups also showed lower target BP achievement rates. We also found a relatively lower application and clinical reflection rate of home or ambulatory BP monitoring.

Chronic tic disorder or Tourette syndrome is known to be a chronic neuro-behavioral disease for which cognitive behavioral therapy (CBT) strategies have recently been introduced. Here, we report the effectiveness of CBT in a case of childhood chronic tic disorder, which is very common in clinical settings. The DSM-IV clinical diagnosis was applied by a child psychiatrist. The Yale Global Tic Severity Scale, Kovac's children's depression inventory, Spielberger State-Trait Anxiety Inventory, Abbreviated Conners' Rating Scales, and the Dupaul ADHD Rating Scales were used. This case involved a pharmacological treatment-refractory patient over the previous year. Thus, psychiatric consultation was undertaken. Subsequently, we administered five sessions of CBT for four weeks, consisting of symptom evaluation and planning, habit reversal training, and ventilation training. Following four weeks of CBT administration, there were improvements in the scores of the Yale Global Tic Severity Scale and the Clinical Global Improvement scale. Our observations indicate that CBT may be effective in the treatment of childhood tic disorder.

This research was carried out to determine the performance rate of health related practices, to measure the agreement between morbidity by doctor's diagnosis and morbidity by 'subject' self-reported and the degree of association between health related practices and morbidity rate by doctor's diagnosis, to identify their effects on morbidity among rural area populations. The data were gathered by volunteer residents(over the age of 20) of Haman Myeon, Haman Gun, Kyeongsangnam Do in Korea, from June 10, 1993 to June 12, 1993 (369 male and 516 female). Face to face interview, lab, chest P-A, EKG and physical examination were completed. Descriptive statistics, agreement analysis and multiple logistic regression procedures were employed for analyses. The results of the study were summarized as follows : 1) Age adjusted morbidity rates by doctor's diagnosis and self-reported were 38.5% (male:37.3%, female:36.5%), 26.4% (male:33.3%, female:27.5%), respectively. Kappa coefficient between morbidity by doctor's diagnosis and morbidity by self-reported was 0.21 (male:0.21, female:0.22). 2) The frequency of disease by doctor's diagnosis was as follows: hypertension (15.3%), gastritis (9.6%), diabetes mellitus (8.5%), liver disease (8.1%), and degenerative arthritis (6.2%) in the study population. 3) Order of health practice performance rate was as follows: Males- normal body weight (62.1%), non-heavy alcohol consumption (57.5%), 7-8 hours of sleeping (50.1%), non-smoking (21.7%), and exercise (19.8%). Females- non-heavy alcohol consumption (97.3%), non-smoking (84.7%), normal body weight (57.8%), 7-8 hours of sleeping (45.0%), and exercise (9.9%). 4) There was no significant relationship between health related practice and morbidity except exercise among health related practices. 5) Health related practice index which was recategorized by high, medium, and low had effects on the probability of developing morbidity.
